I find it hard to believe that nobody else on the list has seen this
problem. I had GL working on both displays in xinerama when Woody was
still testing, but my latest install only has GL working on display 0.
This can be verified with the GL screensavers, as detailed below, but
it affects real applications that I try to run with xinerama. All of
my searching for documented solutions have proved fruitless.
I'm at a complete loss as to where to begin with this. The fact that
it used to work suggests that there's a configuration issue...
Any help is greatly appreciated.
